Benefits of technology

"The present invention is a temporary stain for dental composite material that can be applied to both natural teeth and composite filling material. The stain is easily removed from the natural tooth and is available in solid, liquid, or slurry forms. The stain is made with a curcumin containing material, such as turmeric, and can be used to identify dental composite material in orthodontic procedures or root canals. The stain does not require activating agents or activation steps to be effective. The technical effects of the invention include its ease of use, versatility, and ability to prevent dental practitioners from removing material of the natural tooth."

Problems solved by technology

Unfortunately, composite material which are used for fillings must be removed and replaced for numerous reasons, such as further tooth decay, dramatic damage to the filling, to name a few.
This is often a very difficult task since removal of natural tooth material with the composite material can cause exacerbated damage to the natural tooth necessitating more extensive dental work to repair the same.

example 1

[0037]A piece of composite material (BIS-GMA) was obtained and sliced into disc shaped pieces about 2 ml in thickness. A turmeric powder was diluted with enough water to form a slurry following stirring of the same. The slurry was then applied to the composite pieces and was allowed to set for about 1 to 2 minutes. Following this time, the turmeric slurry was washed away by water and a distinctive yellow stain appeared on the composite pieces.

example 2

[0038]A patient having a damaged composite filling was examined by a dental practitioner. A turmeric slurry was applied to the tooth of the patient having the composite filling. After letting the material set for 1 to 2 minutes, excess turmeric liquid was washed from the tooth and plaque was also removed in the vicinity of the tooth. The composite filling was observed to be about 3 ml in diameter and generally circular in configuration on the side of the tooth, which was a lower left molar. The yellow stain appeared distinctive and allowed the dental practitioner to drill out the stained composite filling. The stain was reapplied to the composite filling and such filling was re-drilled until the composite filling was completely removed. Such reapplication of the stain occurred multiple times. Following removal of the filing, another composite filling was successfully placed in the patients tooth.

example 3

[0039]Pieces of composite material were again formed, as in Example 1. Curcumin containing material was applied to the pieces of composite material and left on a table adjacent to a window. Sunlight was allowed to contact the stained composite material for several hours. After this time period it was noted that the stain on the composite material had vanished indicating that the staining material of the present invention was not colorfast.

Abstract

A stain of dental composite material vanishing under the influence of light which utilizes a curcumin containing material. The curcumin containing material is applied to the filling and the tooth to reveal the extent of the filling material relative to the tooth for the purpose of identification.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a novel and useful stain for dental composite material.[0002]Traditional dental fillings and the like have employed metallic material such as silver, gold, and mercury. Recently composite material have been substituted for the older metallic materials since they enjoy the advantage of mimicking or matching the external coloration of the natural tooth. Unfortunately, composite material which are used for fillings must be removed and replaced for numerous reasons, such as further tooth decay, dramatic damage to the filling, to name a few. In removing such composite fillings, the dental practitioner must discern the position and extent of the composite material relative to the natural tooth. This is often a very difficult task since removal of natural tooth material with the composite material can cause exacerbated damage to the natural tooth necessitating more extensive dental work to repair the same.[0003]In the past, ...
